MAIT engagers: Providing a large therapeutic window for the treatment of solid tumors (AACR 2025) - "MAIT cell engagers are a promising approach for the treatment of solid tumors that have the potency and efficacy of a classical TCE but with a significantly improved cytokine safety profile leading to a larger therapeutic window."

MAIT engagers: Bispecific antibody-mediated redirection of mucosal associated invariant T cells to treat solid tumors (AACR 2024) - "Ex vivo cytotoxicity of tumor-resident MAIT cells using dissociated ovarian cancer samples at "real E:T ratios", MAIT engager-mediated cytotoxicity of patient-derived organoids (CRC) and in vivo evaluation of tumor control will be shown.Conclusions. MAIT cell redirection is a promising approach for the treatment of solid tumors that has the potency and efficacy of a classical TCE but with a significantly improved cytokine safety profile leading to a larger therapeutic window."

BiXAb® MAIT Engagers: solving the problems of classical T-cell engagers in the treatment of solid tumors (SITC 2023) - "Ex vivo cytotoxicity of tumor-resident MAIT cells using freshly isolated ovarian tumor material and MAIT engager-mediated cytotoxicity of patient derived organoids (Colorectal cancer) will be shown. Conclusions The tissue/tumor abundance and potent cytotoxic capability of MAIT cells and the specificity of MAIT engagers (no activation of CD4s/Tregs: reduced CRS and immunosuppression) strongly support the contention that MAIT engagers would have a major, durable response in the treatment of solid tumors."

MAIT Engagers: BiXAb-Mediated Redirection of MAIT Cells to Efficiently Kill Tumors (IO-SUMMIT EUROPE 2023) - "BiXAb-mediated engagement of MAITs (via the unique TCR) and a cancer cell (via a tumor-associated antigen) leads to efficient killing of the tumor cells. This modality does not induce activation of general T cell subsets, in contrast to classical T cell engagers, and promises to significantly impact solid tumors."

MAIT engagers: An efficacious novel modality in the field of T-cell engagers for the treatment of solid tumors (AACR 2023) - "BiXAb® mediated MAIT cell redirection leads to efficient killing of cancer cells and is a promising new approach for the treatment of solid tumors. The iTCR x HER2 BiXAb® has no impact on the general CD8 or CD4 T-cell population which may address some of the clinical limitations of classical TCEs."
